RESILIENT VEHICLE-WHEEL.

`Specification of Letters Patent.

Patented Dec. 6, 191).

Application filed July 18, 1910. Serial No. 572,436.

To all whom 'it 'may concern:

Be it known that I, JOSEPH GAYNOR, a citizen of the United States, and a resident of New York city, Brooklyn, county of Kings, State of New York, have invented new and useful Improvements in Resilient Vehicle-Wheels, of which the following is a specication.

This invent-ion relates to a resilient vehicle wheel provided with spring-actuated spokes vot novel construction thatv insure a smooth and easy running, so that pneumatic or lsimilar. elastic tires may be dispensed wit i.

In the accompanying drawing: Figure 1 is an elevation of part of a vehicle wheel embodying my invention; Fig. 2 a longitudinal section through one ot' the spokes; Fig. 3 a section on line 3-3, Fig. 2; Fig. 4 a section on line 1-41, Fig. 2, and Fig. 5 a section on line 5 5, Fig. 2.

Each spoke is composed of a tubular sleeve having right and left threaded sections 11 which are tapped into an outer and an inner cross head 12. The mechanism intermediate these cross heads and wheel rim 13, as well as hub 111, is substantially identical so that the description ot one applies to the other and like reference numerals have been applied to kindred parts. Each end of sleeve 10 is engaged by a plunger 15 having toot 16 which is provided withl transverse arbors 17 that turn in bearings'18 of a lining plate 19 bolted to rim Upon toot 1b is movably fitted an apertured plate 2O that loosely encompasses plunger 15 and is opposed by a late 21 resting against the corresponding tace of cross head 12. A strong spring 22 bearing with its ends against plates 20, 21 respectively encompasses plunger 15 and the exposed end of sleeve 1O. l

Plunger 15 is centered between a pairot longitudinally arranged bolts 23 and a pair ot transversely arranged bolts 2st. @t these, bolts 23 are swivcled at 25 to lining 19, pass through corresponding apertures ci plate 21 and carry nuts 26 that are accommodated by corresponding openings 27 ot cross head 12. Bolts 24 are tapped at one end into plate ings ot plate 21 and cross head 12 and carry nuts 28 at their other end. Plate 21 is flanked by a pair of outer plates 29' that t'acc rockers 30 tiltable on lining 19. A pair of transversely arranged bolts 31 are sw'veled 20, pass through corresponding open- 'spoke member to the at one end 32 to lining 19 and pass loosely through rocker 30, which is apertured tor the reception ot said bolts. The other ends of bolts 31 pass through openings of plates 29 and carry nuts 33. Intermediate bolts 31 there is tapped into rocker 30 a bolt 34 which passes loosely through plate 29, as well as through cross head 12 and carries anut Bolt 34 is surrounded by a coiled spring 36 bearing with its ends against plate 29 andv rocker 8() respectively. Each spoke-'end constructed as described, is inclosed within a housing 37 having a slip-joint connection with a. cover 38, which is provided with a tubular extension 39 that slidably engages sleeve 10.

y During travel, the weight of the carriage bl-fly will cause a sagging of the axle. This sagging will effect `a telescoping action between the sleeves 10 and plungers 15 ot the bottom spokes, so that all six springs 22 and 36 of such spokes will be simultaneously compressed.' But ther six springs ot the top spokes will also be compressed because the sagging ot the axle will canse a lengthening ot said spokes, By this lengthening, cross heads 12 will recede from their respective lining plates 19, thereby lifting plate 20 and rockers 3() oil toot 16 and plates 19 respectively. As plates 21 and 29 cannot participate in this movement owing to bolt connections 23, 31, springs 22. 36 will be compressed in the manner desired. Simultaneously with the described shortening and lengthening ot the bottom and top spokes, the lateral spokes willbe deflected somewhat out of their normal radial position. rlhis movementot the spokes can take place owing to swivel connections 17, 25, 32 and will likewise cause a compression of springs 3G. ln this way the springs ot' the laterally disposed spokes use also util ized to take up the shock, so that practically all springs are constantly in action.

lt will be seen that by turning sleeve 10 and manipulating the nuts on the springcarrying bolts, the tension ot the springs be easily adj-usted whenever required.

l claim:

1. A resilient vehicle wheel coi'nprising a, rim, a relatively movable hub, a sectional eiipansible spoke, means for pivoting@ one rim, a cross head carried by the other spoke member, and a plurality of springs interposed between said cross head and rim.
